Probably a heckuva lot more than you are paying in GA

I'm in SoCal, and for a basic tune-up here is around $50, without parts... that usually includes truing wheels, cleaning and lubing, replacing cables, and adjusting... total overhauls run about $80-100, but then the bike is pretty much completely disassembled, cleaned, and put back together...

I, myself, try to do as much of the work on my bike as possible... if I can't, it goes to the shop, but that is very very rarely
